The wrongful arrest of tens of thousands of British Muslims after the September 11 attacks can be explained by the very poor intelligence the police had, and, just possibly, excused by the fact that a terrorist action in Britain linked to British Muslims would have been hugely damaging.

We worked to develop our own operations to advance U.S. counterterrorism objectives by penetrating terrorist safe havens and collecting intelligence that would inform policy and enable our own operations.

We can't gather the intelligence we need to foil future attacks, if we are blindly granting terrorists the right to remain silent. But for some reason, we've already done that - with the terrorist who tried to bring down Flight 253.

In the fight against terrorism, national agencies keep full control over their police forces, security and intelligence agencies and judicial authorities.

Our intelligence community needs better coordination of operations and exchange of information, and that's why we need an overall director of national intelligence and a national counterterrorism center.

The PATRIOT Act brought down the wall separating intelligence agencies from law enforcement and other entities charged with protecting the Nation from terrorism.

I strongly support the call to greatly expand our human intelligence capability to penetrate al Qaeda and gather critical intelligence to prevent terrorist attacks on our homeland.

I can tell you that the Canadian intelligence and law enforcement agencies have been providing outstanding co-operation with our intelligence and law enforcement agencies as we work together to track down terrorists here in North America and put them out of commission.

These are Canadian and United States intelligence and law enforcement offices who are working in teams and who are using good intelligence and good law enforcement to really stop the criminals and terrorists before they ever get to the border.

The original PATRIOT Act greatly increased our nation's ability to share intelligence information, made better use of technology, and provided terrorism investigators tools that have long been available in cases involving illegal drugs and organized crime.

Terrorists continue to exploit divisions between law enforcement and the intelligence communities that limit the sharing of vital counterterrorism information.

As a beat reporter covering the CIA and intelligence world after the terrorist attacks of 2001, I could sense that many things I couldn't see or understand were changing, expanding, getting so big they were difficult to manage.

I want to improve TSA's counterterrorism focus through intelligence and cutting edge technology, support the TSA workforce, and strengthen the agency's relationships with stakeholders and the traveling public. All of these priorities are interconnected and are vital to TSA's mission - and I would say, all of our collective mission.

We can no longer expect an Intelligence Community that is mostly male and mostly white to be able to monitor and infiltrate suspicious organizations or terrorist groups.

I do not - I never believed it's better to kill a terrorist than to detain him. We want to detain as many terrorists as possible so we can elicit the intelligence from them in the appropriate manner so that we can disrupt follow-on terrorist attacks.

If the elections are a mere fraud, why are terrorists being trained and infiltrated into India at the command of the Inter-Services Intelligence Agency of Pakistan to kill election candidates and to intimidate voters?

The terrorist uses surprise and stealth, and the only way to defeat that is by having accurate and timely intelligence.

Since 2001, the Patriot Act has provided the means to detect and disrupt terrorist threats against the U.S. Prior to enactment of the law, major legal barriers prevented intelligence, national defense, and law enforcement agencies from working together and sharing information.

One of the great intellectual failures of the American intelligence community, and especially the counterterrorism community, is to assume if someone hasn't attacked us, it's because he can't or because we've defeated him.

The actions that we take on the counterterrorism front, again, are to take actions against individuals where we believe that the intelligence base is so strong and the nature of the threat is so grave and serious, as well as imminent, that we have no recourse except to take this action that may involve a lethal strike.

God is another name for human intelligence raised above all error and imperfection, and extended to all possible truth.

The freedom fighters in India's long struggle for independence from British rule, or members of the African National Congress, were once classed as terrorists. History, as they say, is written by victors, but history also has many cunning corridors - how much time must elapse before all those tricky side-passages are revealed?

What are we fighting the terrorists for if we ourselves do not even stand up for democracy - civil liberties and fundamental rights - which includes independence of the judiciary?

Fear of error which everything recalls to me at every moment of the flight of my ideas, this mania for control, makes men prefer reason's imagination to the imagination of the senses. And yet it is always the imagination alone which is at work.
